The Greek word blasphēmía, represented by G988, is defined as vilification, evil speaking, or railing, especially when directed against God. It appears 19 times across 18 unique verses in the Bible. This term encompasses defamatory and impious speech, highlighting the gravity of words used to dishonor both fellow humans and, most significantly, God himself.
In scripture, G988 is used in several distinct contexts. It is frequently listed among sins that believers are commanded to put away, such as in "evil speaking" that must be removed along with bitterness, wrath, and malice Ephesians 4:31. Jesus identifies blasphemies as evils that proceed from within a person's heart, alongside murders, adulteries, and thefts Matthew 15:19. The term is also used in a legal or accusatory sense, as when the scribes accused Jesus of blasphemy for claiming the authority to forgive sins Mark 2:7. The ultimate expression of this concept is seen in Revelation, where the beast from the sea bears a name of blasphemy and speaks against God (Revelation 13:1, Revelation 13:6).
Several related words help clarify the scope of G988:
- G987 blasphēméō (to blaspheme): This is the verb form of G988, signifying the act of vilifying or speaking impiously. It is used when the high priest accuses Jesus, declaring, "He hath spoken blasphemy" Matthew 26:65.
- G2549 kakía (malice): Defined as "badness, i.e. (subjectively) depravity, or (actively) malignity," this word is often paired with G988 as a foundational evil to be put away by believers Colossians 3:8.
- G2906 kraugḗ (clamour): This term for "an outcry" or "tumult" describes the outward, disruptive expression that often accompanies the internal attitudes of anger and evil speaking Ephesians 4:31.
- G266 hamartía (a sin): As a general term for sin, it provides a broader category for G988. The relationship is highlighted when Jesus states that all manner of sin and blasphemy can be forgiven, with one critical exception Matthew 12:31.
The theological weight of G988 is significant, particularly in how it defines sins of speech and attitude.
- A Sin Originating from the Heart: Scripture presents blasphemy not as a spontaneous slip of the tongue, but as an overflow of a corrupt heart, placing it in the same category as other profound moral evils like murder and adultery Mark 7:22.
- An Affront to Divine Authority: The most serious form of blasphemy is speech that directly challenges the honor and authority of God. This was the charge against Jesus when he claimed a divine prerogative John 10:33 and is the defining characteristic of the satanic beast in Revelation Revelation 17:3.
- The Unforgivable Transgression: The concept is given its utmost gravity in the warning that while every sin and blasphemy can be forgiven, "the blasphemy against the Holy Ghost shall not be forgiven unto men" Matthew 12:31, marking it as a unique and permanent state of rebellion.
In summary, G988 blasphēmía is a powerful term that extends beyond simple profanity. It defines a range of defiant speech, from "railing" and "evil speaking" in human interactions to the ultimate transgression of vilifying God. As a sin that originates from the heart, it serves as a critical indicator of one's spiritual condition and relationship to divine authority, illustrating the profound biblical importance placed on the power of the tongue.
